Instructive demonstration method of a measuring device using a network, and system for the method

ABSTRACT

A measuring instrument information providing server delivers to a user terminal via a network an operational program that contains demonstration information for enabling dynamic and interactive operation of a measuring instrument in response to a request for providing demonstration information on the predetermined measuring instrument from a user terminal and a request for making operation, and causes the user terminal to deliver to a predetermined measuring instrument terminal via the network an operational command that contains demonstration information operated and inputted at the user terminal. The measuring instrument information providing server causes the measuring instrument terminal to control the predetermined measuring instrument connected to the measuring instrument terminal in response to the operational command from the user terminal in order to operate the measuring instrument and to deliver a measurement result obtained by the measuring instrument to the user terminal via the network.

TECHNICAL FIELD

[0001] The present invention relates to an interactive demonstration method for a measuring instrument and system using a network. More particularly, the present invention relates to an interactive demonstration method for a measuring instrument and system using a network in which demonstration of a measuring instrument developed by a measuring instrument manufacturer is dynamically and interactively executed between the manufacturer and a user (person who wants to purchase the measuring instrument) via a network such as an internet.

BACKGROUND ART

[0002] For a company that develops a variety of products and manufactures and sells such developed products, it is an important task to let customers know such products for sale.

[0003] In general, advertisement of these products is carried out by utilizing mass media such as various kinds of newspapers, journals, or TV.

[0004] Hence, for example, advertisement of a measuring instrument for measuring properties of electronic communication equipment or electronic parts is typically carried out by inserting advertisements in their associated journals.

[0005] In this case, in a complicated measuring instrument in which measurement items are diversified, if only measurement items or specifications are described in the advertisement fields of their associated journals, an amount of information is insufficient for a general user who attempts to purchase or install such a measuring instrument.

[0006] To such a user having interest in such a measuring instrument (person who wants to purchase the measuring instrument), a manufacturer of this measuring instrument creates a demonstration video tape having recorded therein demonstration of handling or operation of the measuring instrument, and delivers or gives it to the person who wants.

[0007] The user of this measuring instrument (person who wants to purchase the instrument) mounts the demonstration videotape on one's own video player, and checks the demonstration of handling or operation on a TV screen.

[0008] In addition, a manufacturer of this measuring instrument writes data for demonstration of handling or operation of this measuring instrument into a demonstration CD-ROM, and delivers or gives such a CD-ROM to a person who wants to purchase the measuring instrument.

[0009] The person who wants to purchase the measuring instrument mounts such a demonstration CD-ROM on one's own PC terminal, and checks the data for demonstration of handling or operation on the PC terminal display screen.

[0010] Further, in recent years, there has been implemented a system for distributing to a person who wants via communication network demonstration data for demonstration of handling or operation of a measuring instrument stored in the CD-ROM.

[0011] In this case, the user (person who wants to purchase the instrument) having received distribution of the demonstration data via a communication network, checks information on the handling or operation of the measuring instrument, which was received by one's own PC terminal, on the display screen.

[0012] However, the following problems to be solved have till remained unsolved in each of the above described techniques.

[0013] That is, for example, in a measuring instrument for a variety of modulation signals or in a measuring instrument that carries out waveform analysis or frequency analysis, it is required that a tremendous number of measurement items or measurement conditions are set.

[0014] It is very difficult to generate demonstration data for demonstration of handling or operation which fully covers such a tremendous number of measurement items or measurement conditions, and it is not realistic to generate such demonstration data.

[0015] Even if such demonstration data has successfully been generated, an amount of the data becomes tremendously large, thus requiring a considerable amount of time for a user to search for a portion of one's own interest.

[0016] Further, where the demonstration data is distributed to a person who wants to purchase it via a communication network, the communication time and communication cost significantly increase.

[0017] Furthermore, the demonstration data for handling or operation of the measuring instrument, the data being delivered or distributed via a communication network to the above described person, only concerns demonstration under typical measurement items or measuring conditions which are statistically provided.

[0018] Thus, a user (person who wants to purchase the instrument) cannot check demonstration data for dynamic and interactive demonstration, the data including measurement items, measuring conditions or the like of one's own interest.

[0019] Therefore, the user (person who wants to purchase the instrument) has only a way to operate an actual measuring instrument by oneself at a shop or showroom of the measuring instrument manufacturer or ask a person in charge to operate the instrument.

[0020] On the other hand, in the U.S. Pat. No. 5,790,977, “Data Acquisition from Remote Instrument via Internet”, there is disclosed a technique concerning a system for providing access to measurement of a vector modulation analysis (VMA) instrument or the like from an arbitrary place in the world so as to achieve remote control, data acquisition of measurement results, screen capture, and status, remote diagnostics and many other uses.

[0021] Hence, in a system disclosed in this U.S. Pat. No. 5,790,977 as well, data acquisition can be only achieved of typical measurement items or measuring conditions which are statistically provided, and dynamic and interactive data acquisition including measurement items or measuring conditions of the user's interest cannot be achieved.

[0022] In addition, in the U.S. Pat. No. 5,790,977, there is neither disclosure nor suggestion of a technique for constructing an interactive demonstration system for a measuring instrument using a network in order for a user (person who wants to purchase the instrument) to know the details on various measuring instruments which are newly developed and to acquire dynamic and interactive demonstration information including measurement items, measuring conditions of the user's interest or the like.

BEST MODE OF CARRYING OUT OF THE INVENTION

[0121] Hereinafter, respective embodiments of the present invention will be described with reference to the accompanying drawings.

[0122] (First Embodiment)

[0123]FIG. 1 is a schematic diagram showing a general configuration of a first embodiment to which an interactive demonstration method for a measuring instrument and system using a network according to the present invention are applied.

[0124] That is, as shown in FIG. 1, a measuring instrument information providing server 2, a plurality of user terminals 3, a selling company terminal 4, and three measuring instrument terminals 5 a, 5 b, and 5 c, for example, are connected to an internet 1.

[0125] Individual measuring instruments 6 a, 6 b and 6 c are connected to the measuring instrument terminals 5 a, 5 b, and 5 c, respectively.

[0126] In an interactive demonstration system for a measuring instrument according to the present embodiment, the measuring instrument 6 a is a measuring instrument that has special specifications specified by a customer (user).

[0127] In addition, the measuring instrument 6 b is generally a commercially available W-CDMA signal measuring instrument.

[0128] Further, the measuring instrument 6 c is generally a commercially available microwave signal measuring instrument.

[0129] To each of these generally commercially available measuring instruments 6 b, 6 c, a plurality of measuring objects 8 are connected via a switching circuit 7 in such a way that any of these objects can be selected.

[0130] This switching circuit 7 is controlled to execute switching by the corresponding measuring instrument terminal 5 a, 5 b.

[0131] One example of the measuring objects 8 is a W-CDMA RF chip or cellular phone, for example, where the measuring instrument 6 b is a W-CDMA signal measuring instrument, for example.

[0132] In addition, another example of the measuring objects 8 is a microwave oscillator or microwave relay unit where the measuring instrument 6 c is a microwave signal measuring instrument.

[0133] For example, the measuring instrument information providing server 2 composed of computers is configured as shown in FIG. 2.

[0134] In this measuring instrument information providing server 2, there are incorporated: a communication control section 10; a home page (HP) memory 11; a customer database 12; an operational information storage section 13; an access receiving section 16; a measuring instrument selecting/calling section 17; and a screen/program transmitting section 18.

[0135] This measuring instrument information providing server 2 opens its own home page 19 as shown in FIG. 3, for example, stored in the home page (HP) memory 11 over the internet 1 by way of the communication control section 10 into which a browser is incorporated. In addition, this server accepts access to its own home page 19 from each of other terminals 3, 4, 5 a, 5 b, and 5 c. Further, the server carries out information exchanges with the other terminals 3, 4, 5 a, 5 b, and 5 c.

[0136] Here, the home page (HP) 19 as shown in FIG. 3 opened over the internet 1 is stored in the home page (HP) memory 11.

[0137] On this home page (HP) 19, there are displayed icons 20 a, 20 b, and 20 c of the respective measuring instruments 6 a, 6 b, and 6 c of which a user desires execution of operation. Further, there is displayed a URL (home page address) 21 of a selling company terminal 4 where the user makes an estimate or due date inquiry for the measuring instruments 6 a, 6 b, and 6 c.

[0138] In the operational information storage section 13 shown in FIG. 2, there are stored, for each of the measuring instruments 6 a, 6 b, and 6 c connected to the respective measuring instrument terminals 5 a, 5 b, and 5 c, a front panel screen 14 that is an operating screen for the user to remotely operate each of the measuring instruments 6 a, 6 b, and 6 c at the user terminal 3 via the internet 1 and the corresponding measuring instrument terminal 5 a, 5 b, or 5 c; and an operational program 15 for the user to remotely operate each of the measuring instruments 6 a, 6 b, and 6 c at the user terminal 3 via the front panel screen 14.

[0139] In this operational program 15, there is contained demonstration information for enabling dynamic and interactive operation including measurement items, measuring conditions or the like of interest of the user (person who wants to purchase the instrument) in response to a request for providing demonstration information on a predetermined measuring instrument 6 from the user terminal 3 and a request for making operation.

[0140] A control section 101 shown in FIG. 2 controls each section contained in the above described measuring instrument information providing server 2 based on a program recorded in a program recording medium 102, as described later.

[0141] The front panel screen 14 shown in FIG. 4 schematically illustrates a front panel of actual measuring instruments 6 a, 6 b, and 6 c.

[0142] That is, inside this front panel screen 14 there are displayed a display frame 23 that is a data display area for displaying a measurement result 22; an operating icon 24 a that is an operating portion schematically illustrating various kinds of operational buttons; an operating icon 24 b schematically illustrating an operational knob; and the like.

[0143] Where the user remotely operates a desired measuring instrument by using this front panel 14 at one's own user terminal 3, the operating icon 24 a is clicked by the mouse, or in the case of an operating icon 24 b of the operating knob, a start position or an end position in a rotational direction is repeatedly clicked by the mouse, and the operating knob is virtually rotated.

[0144] The operational program 15 converts a clicking operation of each of the operating icons 24 a and 24 b on the front panel screen 14 by the user into data on normal operation command, and transmits the converted data to the measuring instrument terminal 5 a, 5 b, or 5 c during line connection. In addition, a measurement result 22 received from the measuring instrument terminal 5 a, 5 b, or 5 c is graphically displayed on the display frame 23 of the front panel screen 14.

[0145] In this manner, there is executed an operational program 15 that contains demonstration information for dynamically and interactively operating the measuring instrument including measurement items, measuring conditions or the like of the user's interest concerning the measuring instrument.

[0146] In FIG. 2, the address (home), name, occupation, address (business), E-mail address and the like of each user who accesses to this measuring instrument information providing server 2 are stored in the customer database 12.

[0147] In addition, if an access to the home page 19 from the user terminal 3 occurs, the access receiving section 16 checks a user that is an access source by using the customer database 12, and specifies a measuring instrument 6 for the user's request for making operation.

[0148] The measuring instrument selecting/calling section 17 reads out the front panel screen 14 and operational program 15 that correspond to the measuring instrument specified from the operational information storage section 13.

[0149] The screen/program transmitting section 18 downloads the front panel screen 14 and operational program 15 read out from the operational information storage section 13 to the user terminal 3 in access to the home page 19.

[0150] In FIG. 1, for example, the measuring terminals 5 a, 5 b, and 5 c composed of computers each also have a URL and a home page 25 as shown in FIG. 5, for example.

[0151] A selection icon 26 of a measuring object 8 connected to the measuring instrument 6 a, 6 b, or 6 c operated by oneself is displayed on this home page 25.

[0152] When one measuring object 8 is specified from the user terminal 3 being connected to the measuring instrument terminal 5 b or 5 c by clicking operation for the selection icon 26, the measuring instrument terminals 5 b or 5 c connects the measuring object 8 specified by controlling the switching circuit 7 to switch to the measuring instrument 6 b or 6 c.

[0153] Only one specially specified measuring object 9 is connected to the measuring instrument 6 a, and thus, no switching control is carried out.

[0154] The measuring instrument terminal 5 a, 5 b, or 5 c applies an operational command signal to measuring instrument 6 a, 6 b, or 6 c connected to its own terminal based on an operational command inputted from the user terminal 3 being connected to its own, and operate the measuring instrument 6 a, 6 b, or 6 c.

[0155] A measurement result 22 of the measuring object 8 or 9 outputted from the measuring instruments 6 a, 6 b, or 6 c is returned from each of the measuring instrument terminal 5 a, 5 b, or 5 c to the user terminal 3 that is an access source via the internet 1.

[0156] In FIG. 1, for example, in each user terminal 3 composed of commercially available personal computers (PC), there is incorporated a browser for accessing a variety of home pages opened over the Internet 1.

[0157] Further, in FIG. 1, for example, the selling company terminal 4 composed of computers also has a URL and a home page, and responds to an estimate or due date inquiry from the user terminal 3 via the internet 1.

[0158] Furthermore, in FIG. 1, in a program recording medium 102, there is recorded, as a program for interactive demonstration of a measuring instrument using a network, a program comprising: first computer readable program coding means for, in response to a request for providing demonstration information on a predetermined measuring instrument from a user terminal and a request for making operation, delivering to the user terminal via a network an operational program that contains demonstration information for enabling dynamic and interactive operation of the measuring instrument; second computer readable program coding means for causing the user terminal to deliver to a predetermined measuring instrument terminal via the network an operational command that contains demonstration information for dynamically and interactively operating the measuring instrument operated and inputted at the user terminal based on the delivered operational program; third computer readable program coding means for causing the measuring instrument terminal to control the predetermined measuring instrument connected to the measuring instrument terminal in response to the operational command that contains demonstration information for dynamically and interactively operating the measuring instrument delivered from the user terminal and to deliver a measurement result obtained by the measuring instrument to the user terminal via the network; and fourth computer readable program coding means for causing the user terminal to output the measurement result delivered from the measuring instrument terminal via the network, for example.

[0159] Now, a detailed operation of the measuring instrument information providing server 2, the user terminal 3, and the measuring instrument terminals 5 a, 5 b, and 5 c in the thus configured measuring instrument interactively demonstrating system using a network according to the present invention, will be described with reference to a flow chart.

[0160]FIG. 6 is a flow chart showing an operation of the measuring instrument information providing server 2.

[0161] First, when a power source (not shown) of the measuring instrument information providing server 2 is turned ON, the home page 19 shown in FIG. 3 read out from the home page memory 11 is opened over the internet 1 (step S1).

[0162] If an access occurs to a URL of this home page 19 from one user terminal 3 (step S2), this home page 19 is downloaded to the user terminal 3 that is an access source (step S3).

[0163] When any one of selection icons 20 a, 20 b, and 20 c of the measuring instruments 6 a, 6 b, and 6 c desired by the user on the home page 19 is selected at one's own user terminal 3 (step S4), the front panel image 14 and the operational program 15 of the selected measuring instrument 6 a, 6 b or 6 c inside the operational information storage section 13 are read out, and are downloaded to the user terminal 3 (steps S5 and S6).

[0164] Next, a connection destination of the user terminal 3 is moved to (linked with) each of the measuring instrument terminals 5 a, 5 b, or 5 c of the selected measuring instrument 6 a, 6 b, or 6 c (step S7).

[0165] Then, a line is disconnected from the user terminal 3 (step S8).

[0166] If none of the selection icons 20 a, 20 b, and 20 c of a measuring instrument is selected at the step S4 and if a URL21 of the selling company terminal 4 is specified at the step S9, the connection destination of the user terminal 3 is moved to (linked with) the selling company terminal 4 (step S10).

[0167] Then, a line is disconnected from the user terminal 3 (step S11).

[0168] If a power source (not shown) is turned ON at the user terminal 3, remote operation is carried out for a measuring instrument in accordance with a flow chart shown in FIG. 7.

[0169] When the user inputs a URL of a measuring instrument information providing server 2 by one's own user terminal 3 (step Q1), the home page 19 of the measuring instrument information providing server 2 over the internet 1 is accessed by this user (step Q2).

[0170] Then, the home page 19 received at its own user terminal 3 is displayed on, and is outputted to, a display (not shown) of its own user terminal 3 (step Q3).

[0171] When the user specifies the measuring instrument 6 a, 6 b, or 6 c on this home page 19 (step Q4), the specified measuring instrument is transmitted to the measuring instrument information providing server 2 (step Q5).

[0172] Next, when the front panel screen 14 and the operational program 15 of the measuring instrument 6 a, 6 b, or 6 c specified by oneself are downloaded from the measuring instrument information providing server 2 (step Q6), the user terminal 3 temporarily stores and maintains the downloaded front panel screen 14 and operational program 15 in a storage section (not shown) of the user terminal 3 (step Q7).

[0173] When the thus downloaded front panel screen 14 and operational program 15 have been received, the connection destination of its own user terminal 3 is switched to the measuring instrument terminal 5 a, 5 b, or 5 c of the specified measuring instrument 6 a, 6 b, or 6 c.

[0174] Therefore, in this state, the home page 25 as shown in FIG. 5, the home page being downloaded from the measuring instrument terminal 5 a, 5 b, or 5 c that is a connection destination, is displayed on the display (not shown) of its own user terminal 3.

[0175] Subsequently, operation is executed in accordance with an operational program stored in the storage section (not shown) of its own user terminal 3.

[0176] When the user specifies the measuring object 8 or 9 on the home page 25 by the selection icon 26 (step Q8), the specified measuring object 8 or 9 is transmitted to the measuring instrument terminal 5 a, 5 b, or 5 c that is a connection destination (step Q9).

[0177] When the measuring object 8 or 9 has been selected, the front panel screen 14 of the measuring instrument 6 a, 6 b, or 6 c stored in the storage section (not shown) of its own user terminal 3 is displayed on, and is outputted to, the display (not shown) of its own user terminal 3 as shown in FIG. 4 (step Q10).

[0178] When the user inputs an operational command to the measuring instrument 6 a, 6 b, or 6 c by using the operational icon 24 a or 24 b on this displayed front panel screen 14 (step Q11), this operational command is transmitted to the measuring instrument terminal 5 a, 5 b, or 5 c of the connection destination (step Q12).

[0179] When the measurement result 22 of the measuring object 8 is inputted from the measuring instrument terminal 5 a, 5 b, or 5 c of the connection destination (step Q13), this measurement result 22 is graphically displayed in the display frame 23 of the front panel screen 14 (step Q14).

[0180] When the user operates and inputs a measurement end command (step Q15), the measurement end command is transmitted to the measuring instrument terminal 5 a, 5 b, or 5 c of the connection destination. Then, a line to the associated measuring instrument terminal 5 a, 5 b, or 5 c is disconnected (step Q16).

[0181] When the power source (not shown) is turned ON, measuring instrument terminals 5 a, 5 b, and 5 c each carry out measurement processing for the measuring instruments 6 a, 6 b, and 6 c each in accordance with a flow chart shown in FIG. 8.

[0182] After a line has been connected with a user terminal 3 that is an operation execution request source of the measuring instrument 6 a, 6 b, or 6 c (step R1), when the measuring object 8 is selected by the user terminal 3 (step R2), the measuring instrument terminals 5 a, 5 b, and 5 c each control a switching circuit 7 to perform switching, and connects the specified measuring object 8 to the measuring instrument 6 a, 6 b, or 6 c operated by the measuring instrument terminal 5 a, 5 b, or 5 c (step R3).

[0183] When a measurement operational command is inputted from the user terminal 3 (step R4), each measuring instrument 5 a, 5 b, or 5 c operates the measuring instrument 6 a, 6 b, or 6 c.

[0184] Specifically, each measuring instrument terminal 5 a, 5 b, or 5 c applies a measurement specification signal to the measuring instrument 6 a, 6 b, or 6 c (step R5).

[0185] As a result, the measuring instrument 6 a, 6 b, or 6 c carries out measurement under measurement items and measuring conditions specified by an operational command for the measuring object 8 connected to its own, and delivers the measurement result 22 to the measuring instrument terminal 5 a, 5 b, or 5 c.

[0186] When the measurement result 22 is inputted from the measuring instrument 6 a, 6 b, or 6 c (step R6), each measuring instrument terminal 5 a, 5 b, or 5 c transmits this measurement result 22 to the user terminal 3 (step R7).

[0187] Next, unless a measurement end command has been received from the user terminal 3 (step R8), each measuring instrument terminal 5 a, 5 b, and 5 c returns to the step R4, and waits for a next measurement command operation.

[0188] Then, when a measurement end command is received from the user terminal 3 (step R8), the measuring instrument terminal 5 a, 5 b, or 5 c terminates measuring operation of the measuring instruments 6 a, 6 b, and 6 c, and disconnects a line from the user terminal 3 (step R9).

[0189] In the thus configured measuring instrument demonstrating system using a network, the user operates its own user terminal 3 connectable with the network 1 where a commercially available browser is incorporated in a commercially available personal computer, and provides access to the home page 19 of the measuring instrument information providing server 2, and specifies the measuring instrument 6 a, 6 b, or 6 c, thereby inputting a request for making operation for the measuring instrument 6 a, 6 b, or 6 c.

[0190] Then, the front panel image 14 and operational program 15 as shown in FIG. 4 for operating the measuring instrument 6 a, 6 b, or 6 c are downloaded from this measuring instrument information providing server 2 to its own user terminal 3.

[0191] With a link function of the measuring instrument information providing server 2, its own user terminal 3 is automatically connected to the measuring instrument terminal 5 a, 5 b, or 5 c to which its own specified measuring instrument 6 a, 6 b, or 6 c is connected.

[0192] Actual measuring instruments 6 a, 6 b, and 6 c which are operable by one's own are connected to the measuring instrument terminals 5 a, 5 b, and 5 c, respectively.

[0193] The front panel image 14 having the operating icons 24 a and 24 b and the display frame 23 of the measuring instrument 6 a, 6 b, or 6 c specified by the user, is displayed at the user terminal 3.

[0194] The user remotely operates the measuring instrument 6 a, 6 n, or 6 c specified by operation for mouse clicking the operating icons 24 a and 24 b in the front panel image 14 displayed at its own user terminal 3 via the internet 1 and the measuring instrument terminal 5 a, 5 b, or 5 c.

[0195] Further, the measurement result 22 caused by the user specified measuring instrument 6 a, 6 b, or 6 c is displayed in the display frame 23 of the front panel image 14 of its own user terminal 3.

[0196] In this way, the user can carry out remote operation by specifying arbitrary measurement items and measuring conditions for target measuring instrument 6 a, 6 b, or 6 c with a feeling of visually operating the operating panel of the actual measuring instrument 6 a, 6 b, or 6 c at its own user terminal 3.

[0197] In addition, the user can, of course, arbitrarily select the measuring instrument 6 a, 6 b, or 6 c targeted to be operated from its own user terminal 3, and can arbitrarily select the measuring object 8 of the selected measuring instrument 6 a, 6 b, or 6 c.

[0198] (Second Embodiment)

[0199]FIG. 9 is a connection diagram schematically showing a general configuration of an interactive demonstration system for a measuring instrument using a network according to a second embodiment of the present invention.

[0200] In FIG. 9, like reference numerals designate like elements in the measuring instrument interactively demonstrating system using a network according to the first embodiment of the present invention. A detailed description of duplicate elements is omitted.

[0201] In the interactive demonstration system for the measuring instrument using the network according to the present embodiment, a device or parts manufacturer server 27 is further connected to the Internet 1 in the system according to the first embodiment shown in FIG. 1.

[0202] The device or parts manufacturer server 27 composed of computers has a URL and a home page 28 for product introduction as shown in FIG. 10, for example.

[0203] On this home page 28, there is described a URL 30 of the previously described measuring instrument information providing server 2 that provides measurement service to customers (users) who desire execution of testing the device or parts 29 together with introduction of devices or parts 29 that are products of the device or parts manufacturer.

[0204] Now, an operation of each section in the thus configured measuring instrument interactively demonstrating system using a network according to the second embodiment will be described with reference to a sequence chart shown in FIG. 11.

[0205] First, a user specifies a URL from its own user terminal 3, and provides access to a home page 28 of the device or parts manufacturer server 27 (timing T1).

[0206] When the user specifies a device or parts 29, and then, specifies (clicks) the URL 30 of the measuring instrument information providing server 2, the connection destination of the user terminal 3 is changed to (linked with) the measuring instrument information providing server 2 (timing T2).

[0207] When the user specifies the measuring instrument 6 a, 6 b, or 6 c on the home page 19 of the measuring instrument information providing server 2 by its own user terminal 3 (timing T3), the front panel screen 14 and the operational program 15 of the measuring instrument 6 a, 6 b, or 6 c specified from the measuring instrument information providing server 2 are downloaded to its own user terminal 3 (timing T4).

[0208] Then, the connection destination of the user terminal 3 is changed to (linked with) the measuring instrument terminal 5 a, 5 b, or 5 c of the specified measuring instrument 6 a, 6 b, or 6 c (timing T5).

[0209] On the home page 25 of the measuring instrument terminal 5 a, 5 b, or 5 c, when the measuring object 8 is automatically selected as the device or parts 29 specified on home page 28 of the device or parts manufacturer server 27 (timing T6), the measuring object 8 of the specified device or parts 29 is automatically connected to the measuring instrument 6 a, 6 b, or 6 c (timing T7).

[0210] In this state, a measurement operational command is transmitted from the user terminal 3 to the measuring instrument terminal 5 a, 5 b, or 5 c based on the user operation (timing T8).

[0211] As a result, when a measuring command is delivered from the measuring instrument terminal 5 a, 5 b, or 5 c to the measuring instrument 6 a, 6 b, or 6 c (timing T9), a measurement result 22 of the device or parts 29 (measuring object 8) specified from the measuring instrument 6 a, 6 b, or 6 c is returned (timing T10).

[0212] The measuring instrument terminal 5 a, 5 b, or 5 c returns this measurement result 22 to the user terminal 3.

[0213] The user terminal 3 displays the measurement result 22 in the display frame 23 of the front panel screen 14 (timing T11).

[0214] At a stage when a series of measuring processes terminate, charge payment information is transmitted from the device or parts manufacturer server 27 to the measuring instrument information providing server 2.

[0215] Next, where the user purchases the device 29 by referring to the measurement result 22 of the device or parts 29, the user access a home page of the selling company terminal 4, and delivers an estimate request (timing T13).

[0216] When an estimate is transmitted from the selling company terminal 4 to the user terminal 3 (timing T14), the user orders the device 29 to the selling company terminal 4 via the user terminal 3 based on this estimate (timing T15).

[0217] In the thus configured measuring instrument interactively demonstrating system using a network according to the second embodiment, a user attempting to purchase the device 29 developed by the device or parts manufacturer operates one's own user terminal 3, accesses the home page 28 of the device or parts manufacturer server 27, specifies the device or parts 29, and inputs a test request.

[0218] Then, one's own user terminal 3 is automatically connected (linked) to the home page 19 of this measuring instrument information providing server 2

[0219] Then, when the measuring instrument 6 a, 6 b, or 6 c is specified on the home page 19 of the measuring instrument information providing server 2, its own user terminal 3 is automatically connected to the measuring instrument terminal 5 a, 5 b, or 5 c that is a link destination.

[0220] The measuring terminal 5 a, 5 b, or 5 c carries out measurement by the measuring instrument 6 a, 6 b, or 6 c with the device 29 being specified as a measuring object 8 based on the user remote operation at the user terminal 3.

[0221] In this way, the user can arbitrarily carry out a variety of tests of the desired device or parts 29 by using its own user terminal 3.

[0222] Further, the device or parts manufacturer makes payment for measurement of device or parts 29 to an installer of the measuring instrument information providing server and measuring instrument terminal.

[0223] In this manner, for a manufacturer of the measuring instrument 6 a, 6 b, and 6 c and a manufacturer of the device or parts 29 targeted for measurement, it is possible to provide a measuring instrument demonstrating system which is the most effective in selling strategy.

[0224] As described above, in the interactive demonstration system for the measuring instrument and system using a network according to the present invention, demonstration information concerning demonstration of a variety of measuring instruments developed by a manufacturer of the measuring instrument is informed to users (persons who want to purchase the instruments). In addition, an operational program for enabling operation of the measuring instrument is delivered to a user terminal via a network according to each user access so as to acquire dynamic and interactive demonstration information including measurement items or measuring conditions and the like of the user's interest concerning the measuring instrument.

[0225] Each user operates and inputs demonstration data for dynamic and interactive demonstration including measurement items or measuring conditions and the like of one's own interest in a desired measuring instrument with its own user terminal having general specifications, the user terminal being connectable to a network, thereby making it possible to grasp demonstration of the measuring instrument at one's own terminal.

[0226] In addition, at the provider who demonstrates the measuring instrument as well, dynamic and interactive demonstration information including measurement items, measuring conditions or the like of the interest of the user (person who wants to purchase the instrument) concerning the measuring instrument, can be automatically provided to the user for the purpose of demonstration of predetermined measuring instrument, and the service provided to users can be improved.

[0227] Therefore, as has been described above, according to the present invention, there can be provided an interactive demonstration method for a measuring instrument and system using a network so as to let a user (person who wants to purchase a instrument) know demonstration information concerning demonstration of a variety of measuring instruments developed by a measuring instrument manufacturer via a network and to achieve dynamic and interactive acquisition of demonstration information including measurement items, measuring conditions or the like of the user's interest concerning the measuring instrument.
